Subject: [PATCH v2 00/12] ad_sigma_delta: convert all drivers to device-managed

Well, for lack of a better title that's what this series does.
It merges Jonathan's patches from:
  * https://lore.kernel.org/linux-iio/20210508182319.488551-1-jic23@kernel.org/
    Patch 3/3 was a polished a bit with my comments from that review and also
    to use the devm_ad_sd_setup_buffer_and_trigger() function.
  * https://lore.kernel.org/linux-iio/20210509114118.660422-1-jic23@kernel.org/
    Added only to base the conversion to devm_

The AD Sigma Delta family of ADC drivers share a lot of the logic in the
ad_sigma_delta lib-driver.

This set introduces a devm_ad_sd_setup_buffer_and_trigger() call, which
aims to replace the 'ad_sd_{setup,cleanup}_buffer_and_trigger()' pair.

This helps with converting the AD7780, AD7791, AD7793 and AD7192
drivers use be fully converted to device-managed functions.

Changelog v1 -> v2:
* https://lore.kernel.org/linux-iio/20210510125523.1271237-1-aardelean@deviqon.com/
* add my S-o-b tags on all patches; with @deviqon.com email
  - Note: I'm a little unsure about the correctness of these tags; there
    are a few mixed-in, with Reviewed-by & Signed-off-by; I'm fine if
    Jonathan tweaks these as needed;
* added patch 'iio: adc: ad7192: handle zero Avdd regulator value as error'
* all Fixes patches should be now at the beginning of the series
